Default How to change the differential Oil?

Can anyone please give step by step instructions on how to change the diff oil or if there is a link which shows how, please post it. I am planning in changing my diff oil and use a different combination of oil:friction additive. Maybe this will solve my problem I am having with my differential. Thanks in advance.

Use a 3/8 drive rachet with short extension and no socket to remove the drain plug on the bottom of the differential. Drain fluid and replace plug. The fill plug is on the top passenger side of the differential. Open it the same way and fill it with additive, and then oil until it runs out. If you want to, you can remove the cover and clean the magnet after you drain it, but you will probably need a new gasket which is part #26066456 and costs about $6.
